Interpretive Summary: Tomato chlorotic spot virus and related tospoviruses Tomato spotted wilt virus and Groundnut ringspot virus have recently emerged to cause serious diseases of tomato in south Florida. The emergence of these viruses has followed increases in thrips vector populations. Multiple large-fruited, tospovirus-resistant tomato varieties were evaluated under commercial production conditions in south Florida.
Technical Abstract: Tomato chlorotic spot virus, Tomato spotted wilt virus and/or Groundnut ringspot virus have occurred every season since being introduced to south Florida. With each subsequent season disease severity has increased. Use of insecticides for management of the thrips vector has proven ineffective in preventing recent outbreaks. Resistant cultivars, which are the only effective control, have not been fully tested under field conditions and are not widely grown in southern Florida. Horticulturally acceptable virus-resistant tomato cultivars will provide the foundation for the long term solution to this problem. The first season of commercial field evaluation of resistant cultivars is presented.
